An Investigation of Direct Hydrocarbon (Propane) Fuel Cell Performance Using Mathematical Modeling

Figure 3

The effect of the anode reference exchange current density, (A/m²), on the polarization curve for a direct propane fuel cell model (DPFC) at 150°C and 1 atm. The values of (A/m²) for the above five cases were represented by the following symbols: (i) open circles: 7x10⁻¹ A/m², (ii) solid squares: 7x10⁻³ A/m², (iii) solid diamonds: 7x10⁻⁵ A/m² (reference case), (iv) solid circles: 7x10⁻⁸ A/m², and (v) open triangles: 7x10⁻¹⁰ A/m². All the other parameters were the same as the reference case mentioned in Table 1.
